18 Claims.

This invention relates to pinking machines, and more particularly to a machine of that general type disclosed in my Patent No. 2,159,716 issued May 23, 1939, in which the pinking wheel or the latter. In a preferred embodiment of the invention, I provide a single element in direct driving connection between the cutter wheel and feed member.

It is also a further provide a novel combination and arrangement of Another object of the invention is to provide means for deflecting the larger particles of waste material from the path of rotation of the teeth of the cutter wheel.

It is also a further object of the invention to provide a pinking machine of the above type which will be positive and reliable in practical operation, of long life, and in which maintenance costs are reduced to a minimum.

With the above and other objects in view, the invention consists in the improved pinking machine and in the form, construction and relative arrangement of its several parts, which will hereinafter be more fully described, illustrated in the accompanying drawing and subsequently incorporated in the subjoined claims.

In the drawing wherein I have disclosed one simple and practical embodiment of the invention, and in which similar reference characters designate corresponding parts throughout the several views:

Fig. 1 is a top plane view, certain parts being broken away, illustrating a pinking machine embodying the present improvements.

Fig. 2 is a longitudinal sectional view taken substantially on the line 22 of Fig. 1, and

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

Referring in detail to the drawing, 5 designates a base plate of suitable dimensions having depending longitudinal side flanges 6 integrally cast therewith and adapted to be fitted Within an opening in a work-bench or table (not shown). Any suitable means may be employed for the purpose of removably and rigidly securing said base plate in position upon the bench or table.

There is also provided upon one end of the base plate 5, and preferably integrally cast therewith,

verse walls or webs 8 and 9 respectively, the latter of which is formed with a suitable bearing I6 for the shaft I I to the outer end of which the power driven wheel I2 is fixed. The superstructure 1 is formed at the top and front side thereof which a guard flange I3 for said drive wheel.

To the other or inner end of the shaft I I, a gear or pinion I4 is fixed and is engaged with the teeth of a similar gear I 5, secured to the shaft I6 journaled in spaced bearings suitably formed on the under side of the base plate 5.

introduced the superand through which the gear element periphery formed with the worm gear 22.

. feeding disk 34. This the shaft I6 is provided with the worm 21 in mesh with the teeth of said worm gear. Preferably, a bridging web 28 connects the bearing 24 with the adjacent side wall of the housing for the gear Hi.

The opposite side of the bearing 24 is formed with a seat extension 29 for the reduced end of a stud shaft 39. A cap piece 3| secured upon said extensionencloses the upper portion of said shaft end which is rigidly fixed against rotation by a suitable set screw indicated at 32.

Upon the stud shaft 30 there is mounted for free rotation a drive member 33 for the fabric drive member at one side thereof is formed with the hub .or sleeve extension 35 projecting through a central opening in the disk 34 of appreciably greater diameter than said hub. This disk is also of greater diameter than the drive member 33 and projects upwardly and closely adjacent to the teeth 29 of the pinking wheel l9, through a slot or opening 36 in the base plate disposed transversely thereof and in tangential relation'to the opening IS. The drive member 33 at its upper side has frictional bearing contact with t e lower surface of the pin-king wheel [9, though, it will be understood that if desired, said member and wheel may be provided with inter-engaging teeth for 'the positive transmission of rotation to the member 33 from said .pink-ing wheel. Preferably, suitable anti-friction rollers, indicated at 31, are interposed between the member and itshub 35 and the stud shaft 30.

The end of the is-exteriorly threaded hub Q35 to receive the adjusting'n 3s forthe resiliently .yieldable spider 39, the arms of which have hearing contact against one side of the disk 34 to yieldingly urge the opposite side thereof into frictional contact with theopposed face :of the drive member 33.

To the upper surface of the base 5 a sheet metal cloth guide plate 49, secured by one or more screws 4|, is provided with a circular opening 42 registering with the opening l9"in the base plate and also provided withthe slot 43 which registers with the slot 36 in the base plate. At the outer side of this slot the plate is formed with the downwardly inclined flange having its free edge closely adjacent to the face of the feed disk v34.

support for fabric seams as they :pass beneath the pressure roller, to bexpresently described. It will be noted from reference to Fig. 2, thatthe upper surfaces of the plate 49 and of the cutting wheel l9 are disposed substantially in a common The superstructure 1 also includes arelatively narrow neck portion 45 extending longitudinally of the base plate, inwardly over the pinkin wheel l9 and in vertically.spaced'irelation above the same. This neck terminatesiin a vertically disposed guide sleeve 46 for the cylindrical shank of a yoke 41 extending upwardly therefrom into the lower end of the sleeve 43. An adjusting screw 43 is threaded in the upper end of said sleeve and a'spring, indicated at 49, is interposed between said screw'and the shank of the yoke .41. In said yoke the pressure roller'59 is revolubly mounted and hasperipheral bearing contact'with the teeth of the pinking wheel 19 and with the periphery of the feed wheel 34. Preferably, the periphery of said feed wheel is knurled or milled to afford a positive'feeding engagement with the fabric materials.

Any suitable system of lubrication may be pro- This flangeiprovides a yieldable' issued'patent, and I have also vided for the anti-friction bearings 25 and 31, such as the arrangement of ducts or passages illustrated in dotted lines, which are supplied with the lubricant through a central valved orifice indicated at 5| in the pinking wheel IS.

The plate 49 carries the vertically disposed cloth guide member 52. This member has a slotted base flange 53 receiving a threaded stud on the plate 49 and adapted to be securely fixed in adjusted position with relation to the teeth of the pinking wheel l9 by means of the clamping nut 54. It will be seen that the inner end of this guide'plate 52 extends over the teeth of the pinking wheel and terminates closely adjacent to the inner -side'face of the pressure roller 59. Thus the cloth will be continuously guided to substantially the point of actual engagement by the pinking teeth and particles of waste material carried around by the pinking wheel as it rotates in the direction of feed will be deflected and interferencet'hereby with a sharp cutting action of the pinkin'g'teeth prevented.

In the operation of the above described machine,it will be seenthat "as the pinking wheel 19 is'rotated'by the'trans'mission of power from shaft ll through the gears 14 and I5 and the worm gearing, .said pinkingwheel, by frictional contact withthe periphery of 'member33, rotates said member, which in turn frictionally drives the feed disk 34. This disk having gripping contact with the under side 'ofthe fabric material,

in cooperation with the pressure roller '50, positively feeds said materialtothe teeth of the pinking wheel l9. .Sincethe'feedin'g disk is capable of eccentric displacement relative'to the stud shaft 30 against "the resistance 'of the resilient spider 39, it will automatically "accommodate 'itself to "variations in thickness :or the materials, or in the feeding of 'a multiple number of plies of material to "the pinking wheel. in this manner, I eliminate the .addition'al'drive gearingfor thefeed wheel as shown in the above-identified greatly simplified the mounting and arrangement of the several parts "constituting'the automa'ticfeed mechanism.

The horizontal mounting of "the ,pinking wheel or cutter has many practical advantages. IThus, incomparison'with' the vertical mountingof the pinkin'g wheel, it may beiofirelatively large diameter with "a much greater number of cutting less frequent renewals of the ,ipin'king wheel, but

'thehorizontal arrangement of said w'heelis'less obstructive and affords greater visibility of the work by the operator. 'Also, in the vertical mounting .of the cutter wheeLthe cuttings or waste have *a'tenden'cy tooling to the-cutting teeth and accumulate to-such an'extent'asto seriously interfere with the cutting action. In the present inventiomhowever, due to the horizontal rotation of'the pinking wheel, the. greater portion ofthe 'cuttings'have 'a'i'tendency to continue their movement in' astrai'ght line parallel to the feed of the fabric, which is aided'toa certain extent by centrifugalaction in the movement of the cutter teeth in a divergent arcuate pathfrom the line offeed. Such minor portions of the" waste cuttings. as -may be carried around on the teeth 'of'the cu'tter wl'reeliare intercepted by the guide'plate or blade 5Zanddeflected inwardly so that they cannot accumulate-at the point ofcut and interfere with-the sharp cutting action of the cutter teeth. Thus a -highquality product is insured. Such particles of fine lint as may flnd their way belowthe base plate and accumulate upon the. teeth of the gear 22 will be automatically removed in the rotation of the Worm 21. Thus the possibility of clogging or frictional resistance in the operation of the gearing from this cause is obviated, and the smooth uniform transmission of driving power to the pinking wheel is obtained.

From the foregoing description considered in connection with the accompanying drawing, the construction, manner of operation and several advantages of the described invention will be clearly understood. The several parts of the machine are of more or less standard or conventional form and may, therefore, be produced and cooperatively assembled at comparatively small cost, thus enabling such a machine to be profitably produced and sold at appreciably less cost to the purchaser than machines heretofore devised for this purpose.

I have herein described and illustrated a practical embodiment of the invention, which after prolonged tests, has given highly satisfactory results. It is, nevertheless, to be understood that and construction of the superstructhe mounting of the pressure roller 50, as well as in other details of my present disclosure, the invention is susceptible of more or less modification or change. It is, therefore, to be understood that I reserve the privilege of incorporating the several novel features of the invention in such other alternative structural forms as may fairly be considered to be within the spirit and scope of the appended claims.
